When looking at literature, and trying to analyze a work of it, there are many aspects that need to be looked at. As such, a literary analysis has the purpose of either analyzing a whole work, or a part of it. As such, one of the first things that are analyzed in literary works is the ideas, or themes, that are being described in the work, and this can be done by also analyzing elements within the work.
